8. Pulse generator function
A pulse generator is integrated into the hand-held pendant station. This function is
operated using two keys that can be chosen as required. The keys are defined on the
Configuration menu (Konfiguration) (section 5.1.4).
The default setting is the keys. The pulse generator is also enabled on the
Configuration (Konfiguration) menu.
The default setting is: "Activated" ("Aktiviert").
The operator can send counter pulses to the control system by actuating one of the
two keys. An RS422 driver module is used as the output stage; this contains the output
signals A, /A, and B, /B (see technical data).
If the key is pressed (or the key as defined by
customer) briefly, then 1 clockwise (CW) counter
pulse is sent.
If the key is operated (or the key defined by the
customer) 1 counter clockwise (CCW) counter
pulse is sent.
If one of the two keys is pressed for longer than the delay set (switch over from single
pulse to continuous sequence of pulses), then when this period has elapsed a counter
frequency in the corresponding direction is output. The value for this period and
the frequency are set on the Configuration (Konfiguration) menu (section 5.1.4).
Example: Key for CW is operated for approx.2 seconds.
Delay set = 500ms, counter frequency set = 80 Hz.
